My training is in chemical biology, pharmacology, and enzymology. My scientific interests are focused on characterizing host-pathogen protein-protein interactions as a way to reveal mechanisms of host invasion, immune evasion, and pathogen replication. Target disease areas include picornaviral infections, in collaboration with the DeRisi laboratory, and parasitic diseases including schistosomiasis, trypanosomiasis and leishmaniasis. Within the MS Facility, I have also joined the core OGlcNAc-signaling team who are interested in understanding the significance of OGlcNAc protein modifications in the context of complex disease such as Alzheimer's disease.
